WATERMIST
Watermist is defined as water droplets less than 1mm in diameter.�
How does it work?
Water from the mains or a tank, flows through distribution pipework and is “atomized” to many very fine droplets, as it passes through a water mist nozzle. Many tiny water droplets create a greater total surface area per liter of water.
The smaller droplets absorb the heat from the fire, and lowers the temperature quickly. The fine droplets in and around the fire boils over from water to steam, or water vapor, which is an inert gas. This conversion to water vapor, dramatically increases the volume of water, up by almost 1700 times. The water vapor displaces the oxygen near the fire, and suffocates it.
The droplets that are not converted to water vapor, will wet the surrounding area and prevent the fire from spreading.
Effectively, the fire is attacked from all sides of the Fire Triangle – Heat, Fuel and Oxygen.
Benefits of low pressure water mist
Exploiting water more efficiently has its’ obvious benefits;
- The systems demand less water, smaller water intake or tank
- Smaller dimensions on pipes and fittings
- Easier and faster installation and replacement
- Discrete and space-saving design in corrosion-free materials
- Low maintenance costs due to high quality corrosion free components
- Effective fire suppression solution that attacks all three sides of the fire-triangle simultaneously
- Non-toxic fire extinguishing with reduced water consumption
- Minimal interruption of the daily operation in case of fire
Prev2up Mist Nozzle
For light and ordinary hazard applications, including parking car garages, offices, schools, retail and general public space areas in hospitals, hotels, care home institutions, etc.

Prevent Mist Systems
Automatic low pressure watermist fire suppression systems from Prevent Systems are designed for the fire protection of lives, buildings and/or specific equipment. The systems have been tested and documented for Residential and Domestic applications, as well as of Ordinary Hazard classes OH-1, OH-2 and OH-3. Please see respective datasheets for details and limitations.
The typical water mist system consists normally of these three main components:
- Watermist nozzles, which produces and distributes the watermist that suppresses a fire in an activated area.
- A pump-set to increase the water pressure from the town mains or water tank.
- Pipes & fittings to distribute the water to the nozzles.
